In the 21st century of the information age, with the rapid development of the telecommunications industry, optical cables have been widely used. Implementing pipelineization for optical cables to enhance their effective protection has become inevitable. Currently, the advanced optical cable sheath material in the world - the silicon core tube - has emerged. With its superior performance, low price, convenient construction and long-lasting durability, it has gradually replaced perforated cement pipes, PVC pipes, and HDPE double-wall corrugated pipes, and has become the leading material for optical (electrical) cable sheaths.
In order to adapt to the development of China's telecommunications industry, our company, with our strong technical strength and rich production experience, after years of unremitting efforts, has developed and produced this silicon core tube product.
Its main features are:
By using the multi-machine co-extrusion method, the silicon core layer is synchronously embedded into the pipeline, providing permanent lubrication and never detaching.
2. The friction coefficient of the inner wall is low, allowing optical (electrical) cables to be repeatedly drawn and stretched within the pipeline. Using a blowing machine, under normal circumstances, a single air blow can reach a length of 1,000 to 2,000 meters.
3. Excellent sealing performance, resistant to water and moisture, and also protected from damage by rodents.
4. It has good ring stiffness and toughness. During construction, the bending radius of this pipe should be no less than 10 times its outer diameter.
5. Anti-aging property, resistant to chemical corrosion. Long service life. When buried underground, it will remain unchanged for at least 50 years.
6. Excellent weather resistance, with an applicable temperature range of -40°C to 100°C.
7. Construction is convenient. Not only does it save time, but the project cost is only 38% of that of PVC pipes.
Product specifications and colors
Product specifications
Our company can provide customers with the following specifications of silica core tubes or optical tubes. That is: 50/42, 48/40, 046/38, 040/33, 034/28, 032/26, and various other specifications. We can also produce the silica core tubes of the specifications you require according to your requests.
The color of the product
Our company can produce various solid-colored silicon core pipes. Additionally, we can also embed longitudinal color stripes of various colors on a certain solid-colored pipe, so as to facilitate the parallel laying of multiple pipes and enable easy identification. For example: 1x4, 2x3, 3x2, etc.
Recommended Specifications and Colors
To enhance the antioxidant capacity of the silicon core tubes and extend their service life, we recommend that you use the silicon core tubes with a black (base) color and longitudinal color stripes. Considering the economic aspect of the overall project cost, as well as the ease of product handling, transportation and construction, it has been verified by users in various regions that the 40/33 silicon core tubes, with a length of 2000m per roll, are the best choice for design and construction. Of course, we can also produce products of any length as per your customer's requirements, such as 200m, 1000m, 1500m and 3000m.
